Background / History

Mashu was created by Chaldea in 2002 as a designed test-tube child for its Pseudo-Servant experiment. Her body and Magic Circuits were engineered to match a Heroic Spirit, allowing that spirit to be summoned and fused with her. She spent her first ten years in a sterile environment, receiving knowledge through implanted instruction rather than ordinary education. 933

At age ten, Mashu underwent the fusion ritual with Chaldea's second Heroic Spirit prototype. The summoning succeeded, but the intended fusion initially failed. The Heroic Spirit eventually transferred its power to Mashu through cooperation, making her Chaldea's successful Pseudo-Servant. 31 32

She lived within Chaldea for her entire childhood and was not permitted to experience the outside world. Before becoming a Pseudo-Servant, her body was fragile and her projected lifespan could not exceed eighteen years; at seventeen, she had less than a year remaining and eventually collapsed after concealing her worsening condition. 933 935

Mashu's inherited Heroic Spirit is later identified as Galahad. When Galahad's memories and will begin overwhelming her, Luo Zhen guides her through <Threefold Secret Empowerment>. The ritual lets Mashu control and permanently assimilate Galahad's power rather than merely borrow it; Galahad's lingering emotions and consciousness disappear afterward. 1901 1902 1903

Appearance

Mashu is a slender, graceful girl with smooth, shoulder-length pink hair. Her bangs cover one eye, and she wears plain-framed glasses. 20

• Her Chaldea uniform is white, with a short skirt, stockings, and long boots. 20
• In her initial Servant form, she wears tight purple armor resembling a dress and carries a massive shield. 28
• After awakening Galahad's power, she gains black iron elbow armor, skirt armor, a purple lower cape, and a red-hilted sword at her waist. 1902
• Her Saver transformation changes her battle dress and Cross Shield to holy white. 2597

Personality

Mashu is quiet, earnest, and initially awkward at expressing emotion. Her controlled manner and tendency to speak only when necessary can make her seem distant, but she is genuinely curious, proactive, kind, and pure-hearted. 20

Although she fears combat and does not enjoy fighting, Mashu chooses to face danger when others need protection. She is especially hard on herself when she believes she has failed to protect Luo Zhen, often treating her own safety as less important than his. 20 43 895

Her lifelong confinement gives her a strong longing for the outside world and an especially simple personal wish: to see a real blue sky. 3 1999

Abilities & Skills

Pseudo-Servant Physiology

Mashu is a human who possesses the power of a fused Heroic Spirit rather than a fully spiritual Servant body.

• Can use Servant-level strength, speed, Mana, and defenses while retaining a physical human body. 28 29
• Does not require Mana merely to remain manifested, unlike an ordinary Servant. 31
• Her physical state improves when mobilizing Servant power, allowing Luo Zhen's physical reinforcement Magecraft to enhance her rapidly. 159
• After fully integrating Galahad's power, she requires greater food, rest, and nutrition, but gains sharply improved stamina and recovery. 1904

Shielder Defense

Mashu's Shielder class is a rare non-orthodox class devoted to defending allies and territory. Her greatest strength has always been endurance and protection. 48

• Magic Resistance: A — Can nullify magic circles and great Magecraft; high-level modern Magi cannot directly harm her with Magecraft. 883
• Riding: C — Can skillfully operate mounts, including Wyverns. 830 883
• Self-Field Defense: C — Strengthens her defensive ability while protecting allies or her camp; it does not protect Mashu herself. 883
• Spirit Origin Inheritance: ? — Initially unranked, reflecting her unrealized and uncertain potential. 48 883
• Her shield can block barrages that ordinary Magi cannot endure, repel falling debris, and hold back vast numbers of Dragon Tooth Soldiers alone. 28 29 850

Shield of Determined Resolve

A protective skill that expresses Mashu's refusal to surrender those under her protection.

• Temporarily increases her defense and draws enemy attacks toward her. 883 2455
• Can redirect even attacks aimed at Luo Zhen, including Cu Chulainn's causality-reversing Magic Spear. 883
• Becomes particularly effective when Luo Zhen is the person she is protecting. 2463

Misty Chalk Wall of Time

A defensive skill that shifts its target away on the timeline.

• Lets Mashu evade attacks by making her body temporarily illusory. 883
• Can negate exceptionally difficult attacks, including high-dimensional attacks at sufficient proficiency. 883

Noble Phantasm and White-Walled City

Mashu initially cannot activate her Noble Phantasm because she does not know the true name of the Heroic Spirit whose power she inherited. 47 48

• Her shield later projects a defensive barrier capable of resisting the sustained dragon breath of three giant dragons. 895
• During her awakening, the shield manifests a white walled city formed from spiritrons. 1902
• The fortress pattern is identified with Camelot, the White City of Britain, and can protect those behind Mashu from overwhelming attacks. 1963
• After her awakening, she can access the true power of this Noble Phantasm, though she still requires practice to use it fully. 1903

Unnoticed Intention

A new skill identified after Mashu assimilates Galahad's power.

• Its exact effect is unknown to Mashu at the time it is discovered. 1904

Saver Transformation

Mashu becomes a Saver-class Servant after receiving Luo Zhen's Outer Realm Mana against Goetia.

• Her sacred aura repels Goetia's evil presence and nullifies his attacks. 2597
• She withstands Goetia's direct assault long enough for Luo Zhen to dismantle the light belt sustaining the Humanity Incineration. 2599
• Her transformed shield is described as impossible for Goetia to break through. 2599

Relationships

• Luo Zhen — Her senior, Master, and closest companion. Mashu credits Chaldea with allowing her to meet him, trusts his guidance absolutely, and repeatedly risks herself to protect him. 20 32 43
• Galahad — The Heroic Spirit whose power was fused into Mashu. His memories and emotions initially threaten her identity, but his power ultimately becomes fully her own. 1901 1903
• Olga Marie Animusphere — Chaldea's Director. Olga arranges Mashu's intensive training and later acknowledges her enormous growth. 150 800
• Roman — Chaldea's doctor, who monitors Mashu's health and provides information about her condition. 800 933
• Fufu — A frequent companion who rides on Mashu's shoulder and is present during several of her vulnerable moments. 47 1855

• Bedivere — Witnesses her Galahad-related awakening and recognizes the significance of the White-Walled City. 1901 1902
